Detailed answer

Blackheads, also known as open comedones, are a common form of acne. They occur when hair follicles become clogged with oil, dead skin cells, and bacteria. The clogged pore remains open, allowing the trapped material to oxidize and turn black. Blackheads are a mild form of acne and can often be treated with over-the-counter products containing salicylic acid or benzoyl peroxide. However, if blackheads are persistent or severe, it may be necessary to consult a dermatologist for a targeted treatment plan.
